Fix FFG/EGF export format issues

- FFG .tou name field: use AAMMJJ-ville format (2-digit year, hyphen,
  lowercase city without accents), e.g., "250830-marseille"
- EGF .h country code: use uppercase PC[FR,...] instead of PC[fr,...]
- Unify version numbers: use actual version from properties everywhere
  instead of hardcoded "v0.1"
